FIELD OF THE INVENTION

The present invention relates generally to the field of instant messaging, and more particularly, to accessing information from stored conversations.

BACKGROUND OF THE INVENTION

Instant messaging (IM) is a way of communicating and transferring information between computing devices. Particularly in a corporate setting, instant messaging has become widely used to communicate, via electronic messages, in a timely matter. When a typical IM conversation ends, a transcript of the conversation may be stored in a file system located on the computer of a participant in the IM conversation. This information is not readily discovered and accessible by users of other computing devices.

An example of a conventional method for retrieving such information involves searching for key words or topics that correspond to an IM conversation stored on a central server. Similarly, in a peer-to-peer setting, one computer may directly query another, using key words, search terms, etc., for a matching IM conversation.

SUMMARY

Embodiments of the present invention disclose a method, computer program product, and computer system for searching instant message conversation histories stored in a local file system of a user based on topic indexes. A computer receives, on a first computer, a request to locate a topic. The computer determines a second computer to query for the topic. The computer queries the second computer for the topic. The computer receives identification information of participants of an instant messaging conversation corresponding to the topic. The computer stores, on the first computer, the identification information of the participants and indexing the stored identification information by the topic.

The present invention will now be described in detail with reference to the Figures. FIG. 1 is a functional block diagram illustrating a distributed data processing environment, designated 100, in accordance with one embodiment of the present invention.

In this embodiment of the invention, distributed data processing environment 100 includes multiple computer devices interconnected over network 101. Network 101 may be any collection of resources, including computers, components, connections, and protocols, that will support communication between computing devices, such as computer devices 102A, 102B, 102C, and 102D. Additionally, each computer device has a social network connection or relationship with at least one other computer device. For example, a user of computer device 102A may belong to the same social network as a user of computer device 102B. In the present application, belonging to the same social network includes being a contact in an Instant Messaging program. As depicted, computer device 102A has a social network connection or relationship with computer device 102B, represented by connection 104. Thus, a user of computer device 102A may have a user of computer device 102B listed as an IM contact and the user of computer device 102B similarly may have the user of computer device 102A listed as an IM contact. Computer device 102B has a social network connection to computer device 102C (connection 106), and computer device 102C has a social network connection to computer device 102D (connection 108). Each of computer devices 102A, 102B, 102C, and 102D may communicate with each other in a peer-to-peer (P2P) environment over network 101, for example, when communicating via an instant messaging program. Each of computer devices 102A, 102B, 102C, and 102D may be a laptop computer, tablet computer, netbook computer, personal computer (PC), a desktop computer, a personal digital assistant, a smart phone, or any programmable electronic device capable of participating in instant messaging.

IM index program 110 is a computer program for searching topic based IM conversation indexes in a P2P setting where a user can search for a topic without knowing where the topic is stored and who the participants were. Separate instances of IM index program 110 exist on each of computer devices 102A, 102B, 102C, and 102D and are represented as IM index programs 110A, 110B, 110C, and 110D, respectively. IM index programs 110A, 110B, 110C, and 110D include user interfaces 112A, 112B, 112C, and 112D respectively. User interface 112 receives input from a user (e.g., typed messages, selected options, etc.) and displays received messages to the user. IM index programs 110A, 110B, 110C, and 110D also include indexes 114A, 114B, 114C, and 114D respectively. Index 114 stores a topic of an IM conversation held between two or more participants. Index 114 is accessible to the computer device it resides on and to a computer device socially connected through a network to the computer device it resides on. For example, index 114A on computer device 102A is accessible to computer device 102B but is not directly accessible to computer devices 102C and 102D. Each index 114 comprises a list of topics corresponding to IM conversations. A user of IM index program 110 can establish security settings to allow only computer devices meeting specified criteria to access index 114.

FIG. 2 is a flowchart, depicting operational steps for storing and indexing IM conversations, according to an exemplary embodiment of the present invention.

In an example, an IM conversation occurs between computer device 102A and computer device 102B and corresponds to a single topic. A transcript of the IM conversation may be stored by each participating computer device in association with the topic discussed, subsequently allowing the transcript to be retrieved by someone looking for information on the topic.

When an IM conversation occurs, IM index program 110. e.g., IM index program 110A and 110B in the above example, determines when the IM conversation has ended (step 202). Responsive to determining the instant messaging conversation has ended, IM index program 110 determines at least one topic of the IM conversation (step 204).

In one embodiment, participants of the IM conversation can manually specify a topic of or covered by the conversation. For example, after an IM conversation ends, IM index program 110 may prompt a user, via user interface 112, to enter the topic.

In another embodiment, determining a topic is done automatically by IM index program 110. For example, IM index program 110 may have a predetermined list of topics and match at least one of the topics to the IM conversation by identifying one or more key words used in the IM conversation. In yet another embodiment, a word used most frequently in an IM conversation (excluding common articles such as “the,” “an,” “a,” etc.) may be determined to be the topic of the IM conversation.

IM index program 110 determines participants of the IM conversation (step 206). For example, other than the computer device on which IM index program 110 operates on, at least one other computer device participates in the conversation. IM index program 110 may determine not only the user names of the other participants, but also a corresponding IP address for each device a participant is connecting from, and potentially other contact information (email, phone, etc.). IM index program 110 saves the IM conversation (step 208). More specifically, IM index program 110 saves a transcript of the IM conversation and the identified participants of the conversation. IM index program 110 indexes the saved IM conversation by the determined topic (step 210). Thus, in the above example, each of computer devices 102A and 102B would ultimately have a transcript of the IM conversation indexed by the topic, and each device would reference itself and the other device (or the user of itself and the user of the other device) as a participant in the IM conversation.

FIG. 3 is a flowchart, depicting operational steps of obtaining relevant information through the use of IM index program 110, in accordance with an embodiment of the present invention. For example, a user of a computer device, such as computer device 102C, may want to find conversations pertaining to a specified topic from another computer device, such as the conversation saved on computer device 102A and 102B.

In a searching scenario, IM index program 110 receives a request from a user that specifies a topic to be searched (step 302). For example, a user can enter the topic through user interface 112. IM index program 110 initializes a search for the topic among IM conversation indexes of computer devices that have a social network connection or relationship with the computer device hosting IM index program 110 (step 304). For example, in an example where a user requests computer device 102C to search for a specific topic, IM index program 110C searches indexes of computer device 102B and 102D because both of these devices have a social network connection with computer device 102C. In a preferred embodiment, the social network connection is that a user of each of computer device 102B and 102C is in a contact list of the instant messaging program on computer device 102C.

Thus, after initializing the search, IM index program 110 queries a computer device having a social network connection with the computer device hosting IM index program 110 (step 306). IM index program 110 determines whether an index of the queried computer device contains the topic. Upon receiving a notification from the queried computer device that an index on the queried computer device contains the searched topic, IM index program 110 receives the participants of a conversation corresponding to the searched topic (step 308). In one embodiment. IM index program 110 may send a separate query for the participants after identifying the topic. In another embodiment, the participants might automatically be sent by an instance of IM index program 110 residing on the queried computer device. In either case, receiving the list of participants facilitates the user that performed the query to contact the participants of the pertinent conversation, as the participants might have a special knowledge of the topic by virtue of their participation in said conversation. In an example, if a user inputs a topic to search for on computer device 102C, computer device 102C might query the socially connected computer device 102B. Computer device 102B might have an IM conversation indexed by the searched for topic that occurred between computer device 102B and computer device 102A. Computer device 102C would receive from computer device 102B, the participants (e.g., user names and/or IP addresses, and other potential identifying information or contact information). The user of computer device 102C may use this information to directly contact a participant. In one embodiment, the user may also request the transcript of the IM conversation to learn the actual details of the conversation and/or to confirm that the IM conversation truly pertains to the topic that was searched for.

If IM index program 110 does not find the topic in an index of a queried computer device, IM index program 110 may determine another computer device to query based on a contact list of the hosting computer device.

Once IM index program 110 receives or identifies participants of a conversation corresponding to the searched topic, IM index program 110 stores information indicating that an IM conversation took place between the identified participants and indexes this information by topic (step 310). This ability to store, or index, that an IM conversation took place between participants, where the computer device storing this information is not a participant, expands the ability of every device connected to this network of computers to identify people with a specific type of knowledge. For example, in the scenario where computer device 102C searches for the topic, had computer device 102D searched for the same topic prior to the search by computer device 102C, computer device 102D would not have located anyone with potential knowledge of the topic. However, subsequent to computer device 102C indexing that users of computer device 102A and 102B participated in a conversation related to the topic, a search by computer device 102D would locate the topic on computer device 102C and reveal that computer devices 102A and 102B (or users of computer devices 102A and 102B) participated in the relevant conversation. Thus, the user of computer device 102D might directly communicate with any of the participants. Additionally, knowing an original participant of the IM conversation may allow the user of computer device 102D to query either computer device 102A or 102B for a transcript of the IM conversation.

In one embodiment, if a user of a computing device is not or will not be available, the computer device might offload, or “push”, the stored index to a predetermined computer. For example, computer device 102B may push index 114B, potentially along with the stored IM conversations, to computer device 102C. By pushing index 114B to be included in index 114C, the topic and the IM conversation would still be available to be discovered by a user searching for the topic, for example on computer device 102D.

In another embodiment of the present invention, if IM index program 110 cannot find the topic in an index of a computer device on a contact list of the local computer device, IM index program 110 may direct an instance of IM index program 110 on a queried computer device to search for the topic. The instance of IM index program 110 on the queried computer device, as in normal operation, would begin a query of its own contacts for the topic, and if found, may return the applicable index information to the querying computer device. In such a fashion, the search for a topic may spiral outwardly along social contacts from one computer to the next, until the topic is found.
